In rare cases， iMX.RT1050 board dcdc can't work with the voltage is 0v. But under normal condition，the output is 1.25v with 528Mhz. Power up again the failure is removed.It is a new developed board, I think the overcurrent is more possible . the datasheet metion that dcdc has Over current protection，Over voltage protection and Low voltage detection。
1）Whether some register can record the wrong time？
2) DCDC Register 0 is the settings as follows with reset。whether the 8/11/17 is open or closed?
3)whether it can close the the overcurrent/ low voltage /high voltage or not ? the setting is"1" is right?
